Abstract: Under the circumstance of “carbon peak” and “carbon neutrality”, the demand for environmental-friendly gas insulated switchgears in the market is rising. The paper introduces a 12 kV environmental-friendly gas insulated switchgear which uses a kind of clean gas (dry air or Nitrogen gas) to replace SF6 as the insulating medium to realize its arc quenching and insulation with the help of the vacuum circuit breaker. The optimization of product structure and the union of combing three position switches with circuit breakers make the medium-voltage gas-insulated switchgear structure more reasonable and electrical insulation system better. This product is good for reducing environmental pollution and realizing the goal of “carbon neutrality” at an early date.
Key words: environmental-friendly gas; gas insulated switchgear; carbon neutrality; electrical insulation system
